Not very well-known. 'Cr' mangaer might be a niche or relatively unknown creator in the manga world.

Honestly, I have no clear idea. Maybe it's related to a particular artist or collection of caricatures, but without additional details, it's difficult to tell.

Under weak acidic conditions (pH2 - 4), a color reaction would occur between CrCl4 and N, N-Diethvl- 1,4 -phenediammine (DEPDA) to form a purple complex with obvious spectral characteristics. The mechanism of the reaction was more complicated, and there would be different reaction processes under different conditions. The pH value had a great impact on the sensitivity and sensitivity of the detection of CrVI. Under this weak acid condition, the complex reaction between the two was relatively complete, and a stable color peak could be obtained. In addition, the reaction time, temperature, DEPDA concentration and other factors would also affect the reaction results. Based on this color reaction, some detection methods were established, such as chromicity, atomic absorption spectrum, molecular fluorescence probe, etc. The chromicity method was a relatively simple one. The reaction product was placed in an ultraviolet-visible thermometer to determine the concentration of Chromium-based fluorescence. The molecular fluorescence probe used DEPDA as the fluorescent probe. The combination of Chromium-based fluorescence and DEPDA would cause a change in fluorescence intensity. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The CR comic series stands out for its detailed world-building and diverse range of themes. It can range from action and comedy to drama and mystery, offering something for every kind of comic lover.

I'm not sure specifically what 'cr life story' refers to. It could be the story of someone named 'Cr' or it could be some sort of abbreviation related to a particular field like 'credit' or 'creativity'. More context is needed to give a proper account.
